One trait a plant can have is either red leaves (r) or brown leaves (r). another trait is tall stems (t) or short stems (t). a plant used in a dihybrid cross has the genotype rrtt. what is the phenotype of this plant ? . a. brown leaves , tall stemsb. red leaves , tall stemsc. red leaves , short stemsd. brown leaves , short stems

Answer: Option B. Red leaves, tall stems.

Explanation:

For a given gene there are two or more alternative forms present called as alleles. The alleles of a given gene can either be dominant or recessive.A dominant gene is the one which governs the phenotype in both homozygous and heterozygous condition whereas the recessive gene only gets expressed in homozygous condition.In the given question the allele R (red leaves) and T (tall stem) is dominant and, therefore, RRTt genotype will have red leaves and tall stem.
